Blinker problem

[2003jeepKJ]

2003 Liberty 4x4, Left blinker is blinking faster then the right. Front and rear bulbs and brake light is working.

What is wrong?

Check your repeater bulbs (side markers) on the left front.

Did you change over to winter blinker fluid.
Hope this helps .

Ya usually bulbs will blink faster if one is out.


Blinker fluid changeover helps a lot with this.

Yep. Check blinker fluid first.

Then check that side marker bulb.

Make sure you use HOAT blinker fluid only!

The left-handed kind! :Good or Bad:

Cute, blinker fluid!

I'll try side markers first.

If they work, what else?

Well hyperflashing is usually caused by a low voltage problem. So start with that? Otherwise I'm not completely sure. That happened once when my tail light (aftermarket) was wired incorrectly for me. So I assume anything on that track...which is a lot to check!!

Have you checked all your dual filament bulbs out? Reason I ask is I had the rapid flash symptom and "thought " the left front was working and so suspected the repeater bulb. Come to find out if the repeater bulb is working it can make the dual filament lens look like its working (flashing). Turns out the dual filament bulb (3157 if I remember right) had the turn signal filament burnt out.
If you pull the housing (one screw), may as well check the bulbs (filaments) with an ohm meter to be certain they are good. Remember there are two in each of the 3157s.

Thats really fun when its sub zero! I make a practice of changing both sides and keeping the used good one for a spare.

Good luck.

Do you have a non-Mopar trailer package installed?

I have a similar issue right now...except my turn signal filament isn't burnt out, it's just not working. The other two filament(s) illuminate, making for a very dim blinker. I've tried three different bulbs and swapped the fuse, but it's still not fixed.

Eventually I'll get around to checking the socket with an ohm meter (I've been procrastinating because I've never used one before). If that doesn't shed light on the issue, I don't know what else to try. :think:

try some contact cleaner then apply dielectric grease on the socket. if there is any mositure or crappy contact it could show up like a short when the bulb is in or intermittant Open circuit if the bulb is dim / dimming.

What and where is the repeater bulb?

Is it the side marker bulb or turn signal bulb?

It is the side marker bulb (at least it is on an 03)

And my source is the Factory Service Manual.

NOT! It is the side marker bulb.

Why the hell would you call a side marker bulb a repeater bulb when it doesn't repeat anything. Lol. A flasher repeats.

So do our side markers...

Ask the factory. Thats what it is called in the Factory Service Manual.
